Pindborg tumor, a rare calcified odontogenic tumor, can present atypically without calcifications, challenging initial diagnosis. Pathology is crucial for identifying this benign epithelial tumor, especially in unusual locations like the anterior maxilla.

Area of Science:

Oral pathology
Odontogenic tumors
Radiology

Background:

Pindborg tumor, a rare benign epithelial calcified odontogenic tumor, is typically diagnosed via radiological detection of calcifications.
This tumor commonly occurs in the posterior mandible and has historically been classified into squamous and clear-cell forms with varying prognoses.

Observation:

A 61-year-old male presented with an anterior maxillary Pindborg tumor exhibiting polymorphous characteristics.
The radiographic presentation was nonspecific, and notably, calcifications were absent, complicating the initial diagnostic suspicion.
Histopathological examination confirmed the diagnosis of a poorly-differentiated young odontogenic epithelial tumor.

Findings:

The case highlights diagnostic challenges posed by Pindborg tumors lacking characteristic calcifications.

The anterior maxillary location is atypical for this rare odontogenic neoplasm.

Histopathology remains the definitive method for diagnosing Pindborg tumors, particularly in atypical presentations.

Implications:

This case underscores the importance of considering Pindborg tumor in the differential diagnosis of maxillary lesions, even without typical radiographic features.
Accurate pathological diagnosis is essential for appropriate management and prognosis of odontogenic tumors.
Further research into the diverse presentations of Pindborg tumors may improve early detection and treatment strategies.
